Bumblebees may be smarter than we ever imagined. In a new study, buff-tailed bumblebees successfully figured out how to use a small ball as a ladder to reach sugar hidden in an out-of-reach artificial flower. Remarkably, the insects were not trained to solve the puzzle and had no prior experience with similar tasks. More than 70% of the bees independently discovered the solution, even when obstacles made the challenge more complex. Researchers believe the findings provide the first clear evidence of spontaneous problem-solving in an invertebrate. The study adds to growing evidence that bumblebees possess advanced cognitive abilities, including learning, memory, and possibly even emotions.
